| put grub X down but heard about also using milky spores. what is that and where do you get it and how do you use it. also can it be used in conjunction with grub X? does it get rid of the grubs & beetles? I also use beetle bags and spray seven on the shrubs and tree leaves that the beetles eat |
| Japanese beetles are difficult to control, in part because they fly long distances. The pheromone traps are not recommended because they seem to attract more than they catch. You can try to repel the beetles using a spray containing neem, or you can handpick them (they are sluggish early and late in the day), or you can spray with spinosad or with carbaryl (the active ingredient in Sevin) but this is a contact insecticide with no residual action. You can also use beneficial nematodes or neem sprayed on the lawn in late summer to early fall to kill them at the grub stage. Milky spore disease in granular form is applied to the lawn and a treatment lasts in the soil for many years, but it takes some time to see results. Be sure to read and carefully follow all of the label directions on any product you use. If you are using these then you would not need to use the other grub control product in addition. Unfortunately, most gardeners find they have to tolerate a certain amount of damage, and some years are more severe than others depending on the weather and other conditions. You might be interested in reading the following recent release from Penn State about using alternative methods to control grubs. http://paipm.cas.psu.edu/NewsR... I hope this helps. |
